3 Specific installer safety instructions
Always observe the following safety instructions and regulations.
WARNING
Installation shall be done by an installer, the choice of materials and installation shall
comply with the applicable legislation. In Europe, EN378 is the applicable standard.
WARNING
Provide adequate measures to prevent that the unit can be used as a shelter by small
animals. Small animals that make contact with electrical parts can cause
malfunctions, smoke or fire.
WARNING
▪
Make sure the electrical wiring does NOT obstruct correct reattachment of the
communication box cover. Incorrect reattachment of the communication box
cover might result in electrical shocks, fire, or terminal overheating.
▪
Do NOT connect the power supply wires to the terminal block for the
transmission wiring. Incorrect connection is very dangerous, results in damage,
and possible burnout of the electrical components.
▪
Do NOT use stranded wires with a solder finish applied. A loose wire or other
abnormalities might cause abnormal heating.
WARNING
▪
When opening the front plate of an outdoor unit during operation, be careful of a
rotating fan. The fan continues rotating for a while even after the operation is
stopped.
▪
Before turning ON the power supply, make sure that the operation switch of the
outdoor unit is turned OFF. You can check this via the inspection hole of the
electrical component box (middle) of the outdoor unit.
▪
After turning ON the power supply, operate the push buttons and check the LED
indication via the inspection hole of the electrical component box (middle) of the
outdoor unit. Operating with the cover open might cause an electrical shock.
▪
For more information on how to configure the monitoring system (field supply),
see the manual of the supplier.
WARNING
▪
Do NOT turn ON the power when the communication box cover is open. An
electrical shock might occur.
▪
Before turning ON the power, make sure that the communication box cover is
closed.
CAUTION: Precautions when setting the slave address
▪
Do NOT set the same slave address for devices connected to the Modbus master
device.
▪
Apart from the slave address set in the communication box, there are 2 other
slave addresses that cannot be set. When the slave address on the PCB for the
outdoor unit (A2P) is set to "A", slave addresses "A+1" and "A+2" CANNOT be set.
Slave address "A" is used for the outdoor unit, "A+1" is used for the capacity up
unit, and "A+2" may NOT be used.
